The present invention relates to a food vessel packing apparatus having a vacuum packing function, which thermally bonds a film to a top of a food vessel to seal the food vessel. As illustrated in FIGS. 1 to 4, the food vessel packing apparatus of the present invention includes a base 10, a cover 20, a first heater 30, a heating plate 40, a gasket 50, and a vacuum pump 60.

An accommodating groove 11, in which a food vessel 90 is accommodated, is formed concavely in a downward direction at a top of the base 10.

The cover 20 covers the top of the base 10, and in the embodiment, one end of the cover 20 is rotatably hinge-coupled to one end of the base 10.

Unlike the embodiment, the cover 20 may be vertically mounted on the top of the base 10 to be ascendable/descedable.

The first heater 30 is mounted on a bottom of the cover 20, and thermally bonds a film 91, disposed at a top of the food vessel 90, to a top border of the food vessel 90.

The first heater 30 is provided in a closed-curve shape, for thermally bonding the film 91 to a border of the food vessel 90.

The first heater 30 may be directly mounted on the bottom of the cover 20, or as in the embodiment, the first heater 30 may be mounted on the bottom of the cover 20 through the heating plate 40.

The heating plate 40 is provided in a flat plate shape. The first heater 30 is mounted on a bottom of the heating plate 40, and a top of the heating plate 40 is supported by the bottom of the cover 20.

Further, the heating plate 40 is elastically supported by an elastic member 45, disposed between the heating plate 40 and the cover 20, in a direction vertical to the cover 20.

Therefore, the first heater 30 which is mounted in a closed-curve shape on the bottom of the heating plate 40 may be supported by the elastic member 45 together with the heating plate 40, and may move in a vertical direction.

The elastic member 45 may be implemented as a spring, or implemented as a hollow rubber.

The gasket 50 is provided in a closed-curve shape, and disposed along a circumference of the first heater 30 and outside the first heater 30.

The gasket 50 is mounted on the bottom of the cover 20 or the top of the base 10.

The vacuum pump 60 is mounted on the base 10 or the cover 20, and a sucking port 15 is disposed inward from the gasket 50 having a closed-curve shape.

Depending on the case, the vacuum pump 60 may be included in a separated apparatus, and used in connection with the sucking port 15.

The sucking port 15 may be disposed inward from the gasket 50, but preferably, the sucking port 15 may be disposed between the gasket 50 and the first heater 30.

Further, the sucking port 15 may be formed at the base 10 as in the embodiment, or formed at the cover 20.

Moreover, a vessel supporting member 70 that is mounted on the top of the base 10 and supports the border of the food vessel 90 may be mounted on a circumference of the accommodating groove 11.

In this case, a supporting groove is formed at the circumference of the accommodating groove 11, and the vessel supporting member 70 may be preferably inserted into and disposed in the supporting groove 13.

The vessel supporting member 70 is tiltably mounted on the base 10 in a rotation direction of the hinge-coupled cover 20.

To this end, a tilt projection 71 is protrusion-formed at a bottom of the vessel supporting member 70 or the top of the base 10, and the vessel supporting member 70 rotates about the tilt projection 71 to thereby be tilted.

In the embodiment, as illustrated in FIG. 3, the tilt projection 71 is formed at a lengthwise center at the bottom of the vessel supporting member 70.

FIG. 3 illustrates a state in which the vessel supporting member 70 is detached from the base 10, and turned over.

The vessel supporting member 70 is tilted with respect to the tilt projection 71 by an external force like a seesaw.

The vessel supporting member 70 may be provided in a hollow tetragonal shape communicating with the accommodating groove 11 as in the embodiment, or provided in a hollow circular shape depending on a shape of the accommodating groove 11.

Moreover, the vessel supporting member 70 may be provided in the form of two rods depending on the case, and disposed at both sides of the accommodating groove 11.

Further, a pressurizing rubber 81 may be mounted on a bottom of the other end of the cover 20 and outside the gasket 50, and the second heater 82 may be mounted on a top of the other end of the base 10, at a position corresponding to the pressurizing rubber 81, and outside the gasket 50.

The pressurizing rubber 81 and the second heater 82 are not used to thermally bond the food vessel 90 but are used to vacuum-pack food in a separate vinyl bag 92.

Hereinafter, an operation process of the present invention having the above-described configuration will be described.

FIG. 5 is a cross-sectional view illustrating a state in which a food vessel is accommodated in an accommodating groove of the food vessel packing apparatus according to an embodiment of the present invention, and a film is disposed therein, FIG. 6 is a cross-sectional view illustrating a state which is covered and vacuumized by the cover in the state of FIG. 5, FIG. 7 is a cross-sectional view illustrating a state in which the film is thermally bonded to the food vessel in the state of FIG. 6, and FIG. 8 is a cross-sectional view illustrating a state in which a vinyl bag is vacuumized by the food vessel packing apparatus according to an embodiment of the present invention.

When intending to thermally bond the film 91 to the top of the food vessel 90 to seal the food vessel 90, as illustrated in FIG. 5, the food vessel 90 containing food is inserted into and disposed in the accommodating groove 11.

Further, the film 91 is disposed on the top of the food vessel 90.

In this case, an embossing is formed at the film 91, and enables air to flow between the film 91 and the food vessel 90.

In this state, the top of the base 10 is covered by rotating the cover 20.

When the top of the base 10 is covered by rotating the cover 20, the heating plate 40 and the vessel supporting member 70 contact each other from a portion adjacent to the one end of the cover 20 and the one end of the base 10 which are hinge-coupled to each other.

Therefore, when the cover 20 fully covers the top of the base 10, the heating plate 40 and the vessel supporting member 70 are provided with a relatively great compressive force at the portion adjacent to the one end of the cover 20 and the one end of the base 10 which are hinge-coupled to each other, and the heating plate 40 and the vessel supporting member 70 are provided with a relatively small compressive force at a portion adjacent to the other end of the cover 20 and the other end of the base 10.

Therefore, a durability of a component can be reduced by a great force at a specific portion in which a compressive force is greatly applied between the heating plate 40 and the vessel supporting member 70. Also, the first heater 30 is partially detached from the film 91 at a portion in which a relatively small compressive force is applied, and for this reason, the first heater 30 cannot thermally bond the film 91 to the food vessel 90 appropriately.

However, in the present invention, the vessel supporting member 70 is tilted by the tilt projection 71 like a seesaw, and thus, as illustrated in FIG. 6, when the cover 20 covers the top of the base 10, the vessel supporting member 70 rotates clockwise with respect to the tilt projection 71, and is thereby disposed to be downward inclined toward a portion in which the one end of the cover 20 and the one end of the base 10 are hinge-coupled to each other.

At this time, the heating plate 40 also rotates clockwise together with the vessel supporting member 70.

Therefore, an almost uniform force is overall applied to the heating plate 40 and the vessel supporting member 70, and can prevent a durability of a component from being reduced because a pressing force concentrates on a specific portion, thus preventing a problem that the film 91 is not thermally bonded to the food vessel 90 due to the partial detachment of the first heater 30.

That is, as the cover 20 is closed, the vessel supporting member 70 rotates, and thus, an almost uniform force is applied between the heating plate 40 and the vessel supporting member 70. Accordingly, an entirety of the first heater 30 is closely adhered to the film 91, and thus, the first heater 30 can better thermally bond the film 91 to the food vessel 90 overall to seal the food vessel 90.

As illustrated in FIG. 6, when the cover 20 is closed, the food vessel 90 is shut off from the outside by the gasket 50 having a closed-curve shape.

At this time, the cover 20 is attachably/detachably coupled to the base 10 by a locking means (not shown).

In this state, when the vacuum pump 60 operates, the internal air of the food vessel 90 is sucked into the sucking port 15 through a space between the food vessel 90 and the film 91, and then emitted to the outside.

When the internal air of the food vessel 90 is emitted to the outside, power is applied to the first heater 30, which thermally bonds the film 91 to the border of the food vessel 90 to seal the top of the food vessel 90.

Through such an operation, the food vessel 90 may be internally vacuumized and sealed, and thus, food stored in the food vessel 90 can be kept for a longer time.

Further, when it is not required to vacuumize the food vessel 90, the first heater 30 thermally bonds the film 91 to the border of the food vessel 90 without operating the vacuum pump 60.

When intending to vacuum-seal the vinyl bag 92 with an opening formed at one surface, as illustrated in FIG. 8, with the opening of the vinyl bag 92 being disposed in the gasket 50, the vacuum pump 60 operates to vacuumize the inside of the vinyl bag 92, and then the second heater 82 operates to thermally encapsulate the opening of the vinyl bag 92.
